Apparently, my point sailed right over your head.
That information was sealed by the court. Even Ryan's ex-wife wanted to keep it sealed. Another judge broke the seal, for no reason other than to embarrass Ryan and help Obama.
Clinton's dalliance with Lewinsky was not under court seal. But as far as I'm concerned, he crossed the line only when he threatened other women to keep quiet, and especially when he committed perjury and lied about it under oath.
This particular threat against Romney is probably a hoax. But if it isn't, I doubt Obama is directly involved -- he would have to be an idiot to not maintain plausible deniability. But, it was almost certainly someone in his reelection campaign, and I hope Obama remembers what happened to Nixon when he tried to cover up a two-bit burglary that he didn't authorize or even know about.
You missed my point, which was that the issue of how the information comes out is irrelevant. The onus still remains entirely on the candidate who risks his party's victory in the election on his ability to keep something he did secret that would severely impact his ability to win at the ballot box.
